Description

Technical Field

[0001] The present invention relates to the technical field of broiler chicken breeding, and particularly to a cultivation and breeding technology for special chickens as raw materials for Bobo Chicken. Background Art

[0002] As a representative product of Sichuan cold food, the unique flavor and taste of Bobo Chicken highly depend on the quality of chicken raw materials. Currently, commercially available broiler chickens generally have defects in meat quality and flavor: fast-growing white - feather broilers have thick muscle fibers and insufficient flavor substances; local yellow - feather chickens have a long breeding cycle and excessive fat deposition; the meat of culled laying hens is too tough, and all of them are difficult to meet the core requirements of Bobo Chicken for being crispy, tender, juicy and fragrant.

[0003] Traditional broiler chicken breeding models also have many problems in aspects such as drug residue control, precise nutrition regulation and environmental management. The excessive use of antibiotics in conventional breeding leads to excessive drug residues in chicken meat, and for Bobo Chicken as a cold food product, the potential food safety hazards are more prominent. At the same time, existing feed formulations often fail to be optimized for the meat quality characteristics required by Bobo Chicken, and the imbalance of energy - protein ratio leads to abnormal muscle fat deposition and insufficient accumulation of flavor precursor substances. The stress response in high - density breeding environments further exacerbates meat quality deterioration.

[0004] Therefore, developing a special chicken cultivation technology for the special needs of Bobo Chicken, and establishing a complete technical system from the breeding source to the table through multi - trait genetic selection, precise nutrition regulation and healthy breeding management have important practical significance for improving the industrial level and meeting the consumption upgrade. Summary of the Invention

[0005] In view of the above - mentioned deficiencies in the prior art, the broiler chickens obtained by the cultivation and breeding technology for special chickens as raw materials for Bobo Chicken provided by the present invention can meet the requirements of Bobo Chicken for tender, crispy, juicy, chewy and fragrant chicken.

[0006] To achieve the above - mentioned invention object, the technical solution adopted by the present invention is: a cultivation and breeding technology for special chickens as raw materials for Bobo Chicken, including the following steps:

[0007] S1, chicken breed cultivation: Using Emei Black Chicken as the male parent and Sasso Chicken as the female parent for hybridization to obtain the F1 generation chicken breed; then hybridizing the F1 generation chicken breed with Rongde Small Black Chicken to cultivate special chicks suitable for Bobo Chicken;

[0008] S2, flat - rearing of chicks: Transfer the cultivated chicks to a net - bed for flat - rearing, control the temperature and humidity in the house, and equip feeding equipment;

[0009] S3, ground - rearing during the growing period: When the weight of the chicks reaches more than 1 jin, transfer them to a free - range area for free - range farming, and set up corresponding activity spaces and sports fields;

[0010] S4, Feeding Management: including light management, feeding management, group management and rotational grazing in different areas;

[0011] S5, Disease Prevention and Control: This includes vaccination and environmental disinfection.

[0012] Furthermore, in the above-mentioned breeding and raising technology for special chickens for raw materials of Bobo Chicken, in S2, the height of the net bed is 60-80 cm and the mesh diameter of the net bed is 1-2 cm.

[0013] Furthermore, in the above-mentioned breeding and raising technology for special chickens for raw materials of Bobo Chicken, in S2, the temperature inside the house is controlled at 33-35℃ when the chicks are 1-3 days old, and the temperature is reduced by 2-3℃ every week until the temperature inside the house is 21-25℃.

[0014] Furthermore, in the above-mentioned special chicken breeding and raising technology for raw materials of Bobo Chicken, in S2, the humidity in the house is controlled at 60%-65% when the chicks are 1-10 days old, and the humidity in the house is adjusted to 50%-60% after the chicks are 10 days old.

[0015] Furthermore, in the above-mentioned special chicken breeding and raising technology for raw materials of Bobo Chicken, in S3, the activity space for each chicken in the free-range area is not less than 5 square meters, and a fence with a height of 1.5-1.8 meters is set up around the free-range area.

[0016] Furthermore, in the above-mentioned breeding and raising technology for special chickens for raw materials of Bobo Chicken, in S4, the lighting management is to use 24 hours of lighting for the first 1-3 days of brooding, and then gradually reduce it to 23 hours after the 4th day.

[0017] Furthermore, in the above-mentioned special chicken breeding and raising technology for raw materials of Bobo Chicken, in S4, the chicks are fed complete feed for the first 30 days, with feed and water supplied 24 hours a day.

[0018] Furthermore, in the above-mentioned breeding and raising technology for special chickens used as raw materials for Bobo Chicken, the vaccination program in S5 includes the administration of Marek's disease vaccine, Newcastle disease-infectious bronchitis quadrivalent inactivated vaccine, avian influenza trivalent inactivated vaccine, Newcastle disease-infectious bronchitis bivalent live vaccine, and infectious laryngotracheitis recombinant fowlpox virus genetically engineered vaccine.

[0019] Furthermore, in the above-mentioned special chicken breeding and raising technology for raw materials of Bobo Chicken, S5, environmental disinfection involves disinfecting the chicken house and breeding site weekly, and adding probiotics and vitamins.

[0020] The beneficial effects of this invention are as follows: The special chicken breeding and raising technology for the raw materials of Bo Bo Chicken provided by this invention, through the three-line matching breeding of Emei Black Chicken, Saso Chicken and Rongde Little Black Chicken, gives full play to the excellent characteristics of each chicken breed. The special chickens bred are tender and juicy, with rich aroma and even distribution of intramuscular fat. They can better absorb the soup and seasonings of Bo Bo Chicken, thereby significantly improving the taste and flavor of Bo Bo Chicken and meeting consumers' demand for high-quality food.

[0021] In terms of breeding methods, a combination of free-range and ground-raised methods is adopted. This ensures the healthy growth of chicks in the early stages, while the later free-range grazing in high-altitude or forest areas increases the chickens' exercise, resulting in firm "run-up meat" that is more tender and chewy. The free-range method effectively reduces the contact between the chickens and feces through the net bed design, reducing the risk of disease transmission, while the ground-raised method makes full use of the natural environment and ecological resources, reducing feed costs while improving chicken meat quality, thus achieving the dual goals of high efficiency and ecological sustainability.

[0022] In terms of disease prevention and control, this invention has established a scientific vaccination plan and daily disinfection measures. Through strict immunization procedures and regular environmental disinfection, the incidence rate and drug usage in chicken flocks have been significantly reduced, ensuring that chicken meat is free of drug residues and meets healthy food standards. Furthermore, the zoned rotational grazing and ecological free-range models not only reduce environmental pollution but also maintain ecological balance, achieving sustainable farming. Through scientific feeding management, including light control, flock management, and nutritional adjustments, the growth uniformity and survival rate of chicken flocks have been further improved, reducing farming costs. Detailed Implementation

[0023] The specific embodiments of the present invention are described below to enable those skilled in the art to understand the present invention. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they are within the spirit and scope of the present invention as defined and determined by the appended claims. All inventions utilizing the concept of the present invention are protected.

[0024] This embodiment provides a breeding technology for chickens specifically suited for Bobo Chicken. This technology employs a three-line breeding method, leveraging hybrid vigor to cultivate a specialized breed suitable for Bobo Chicken. First, Emei Black Chicken is selected as the first parent, due to its adaptation to the cold, high-altitude environment and its delicious, chewy meat. Second, Sasso Chicken is selected as the second parent, characterized by its fast growth rate and thick meat. Finally, Rongde Black Chicken is selected as the third parent to increase egg production and industrialization benefits. During crossbreeding, Emei Black Chicken is crossed with Sasso Chicken to obtain the F1 generation, which combines excellent meat quality and growth rate. The F1 generation is then crossed with Rongde Black Chicken to ultimately cultivate a specialized breed suitable for Bobo Chicken. This breed not only grows rapidly and has excellent meat quality but also meets the needs of large-scale farming.

[0025] In terms of breeding methods, this technology combines floor rearing and ground rearing. The floor rearing stage mainly takes place inside the chicken house, using a wire mesh floor rearing method. The chickens are raised on wire mesh beds 60-80 cm above the ground to reduce contact with feces and lower the risk of disease. The wire mesh bed material is galvanized iron wire mesh or plastic mesh, with a mesh diameter of 1-2 cm and smooth edges to prevent scratching the chickens. The chicken house needs good insulation, ventilation, and lighting performance; the roof and walls need to be insulated to avoid excessive temperature differences. It is also equipped with feed troughs, waterers, heating equipment, and lighting equipment to ensure a stable growth environment for the chickens. After the chicks enter the house, they are allowed to rest for 1-2 hours before being provided with warm water (with 5% glucose and electrolytes added). Feeding begins 2-3 hours after drinking, initially using high-quality chick feed, given in small amounts frequently. For the first 1-3 days, maintain the indoor temperature at 33-35℃, then decrease it by 2-3℃ each week until it reaches 21-25℃; control the humidity at 60%-65%, and adjust it to 50%-60% later.

[0026] The free-range stage begins when the chicks weigh over 1 jin (approximately 500 grams). Choose a high, dry, and quiet mountainous or woodland area as the grazing ground, ensuring each chicken has at least 5 square meters of space. A 1.5-1.8 meter high fence should be erected around the area to prevent escape and damage from animals. The chicken coop should be built on higher ground, providing rain protection, insulation, and ventilation. Bedding or perches should be provided on the ground, designed for 8-10 chickens per square meter. An exercise area at least twice the size of the coop should be provided outside, planted with trees or with resting sheds to provide shade and rain protection for the chickens. During free-range grazing, the chickens feed on leftover rice paddies and insects in the woods, resulting in ample exercise that helps develop firm, "run-away meat," making the meat tender, juicy, and flavorful.

[0027] In terms of feeding and management, provide 24-hour lighting for the first 3 days of brooding, using warm-colored energy-saving lamps. The bulbs should be 1.5 meters above the wire mesh or ground, with two bulbs per 20-30 square meters of chicken house. From the 4th day onwards, gradually reduce the lighting time to allow the chicks to adapt to natural light patterns. For the first 30 days, feed them complete chick feed, providing food and water 24 hours a day to ensure free access to food. Regularly check feed troughs and water troughs daily, promptly removing leftover feed and spoiled water. When managing by group, separate chicks by sex and strength to avoid fighting and ensure each chick receives sufficient food and space to move around. For the first 2-3 days of free-range rearing, add multivitamins or vitamin C to the feed or water to prevent stress. During the initial free-range period, increase supplemental feed as chicks have poor foraging abilities. When implementing rotational grazing, divide the grazing area into multiple zones, rotating between zones after one month to maintain ecological balance.

[0028] Disease prevention is a crucial aspect of poultry farming. Vaccination must be strictly followed according to the schedule: Marek's disease vaccine at 1 day old; Newcastle disease and infectious bronchitis quadrivalent inactivated vaccine at 7 days old; recombinant avian influenza (H5+H7) trivalent inactivated vaccine at 14 days old; Newcastle disease and infectious bronchitis bivalent live vaccine at 21 days old; infectious laryngotracheitis and infectious fowlpox virus genetically engineered vaccine at 28 days old; Newcastle disease and infectious bronchitis bivalent live vaccine at 65 days old; fowlpox live vaccine at 80 days old; recombinant avian influenza (H5+H7) trivalent inactivated vaccine at 90 days old; and Newcastle disease and infectious bronchitis H52 vaccine at 105 days old. For intramuscular injection, appropriate syringes and needles must be selected to ensure accurate injection; nasal drops should be administered using specialized tools; for drinking water immunization, the vaccine must be mixed into the drinking water according to the prescribed ratio, and the drinking water system should not be disinfected for the first 3-5 days.

[0029] Routine prevention includes maintaining a clean and hygienic breeding environment, cleaning chicken coops and removing manure and debris daily, and conducting thorough disinfection of the coop and grounds weekly using disinfectants such as peracetic acid and benzalkonium chloride. Strengthen health monitoring of the flock, observing their mental state, feed intake, and fecal morphology, and promptly isolating and treating any abnormalities. Regularly add probiotics and vitamins to feed or drinking water to enhance immunity. Simultaneously, implement measures to prevent rodent, snake, and weasel attacks to avoid harming the chickens.

[0030] By implementing the above breeding and raising techniques, we can produce special chickens for Bo Bo Chicken that are tender, flavorful, safe, and healthy, meeting the demand for high-quality raw materials and enhancing the market competitiveness of Bo Bo Chicken.
